The volume of both of these trapezoidal prisms is 24 cubic units. Their heights are 6 and 8 units, as labeled. What is the area of a trapezoidal base of the prism with a height of 6 units?
Answer:
area of a trapezoidal base of each prism with heights 6 and 8 units are 4 square units and 3 square units respectively
Step-by-step explanation:
Let us first be aware of formula of volume for any regular geometrical figure.
Fundamental formula for volume for any regular geometrical figure is.
volume = area of cross section of object* height of object (A)
In the problem stated area of cross section of object will be area of a trapezoidal base.
Given in the question is
Volume of both the trapezoidal prisms = 24 cubic units
*************************************************************************************
For prism with height 6 unit
Substituting the value of height and volume in formula for trapezoidal prisms
24 = 6 * area of a trapezoidal base
=> area of a trapezoidal base = 24/6 = 4 square units
*************************************************************************************
For prism with height 8 unit
Substituting the value of height and volume in formula for trapezoidal prisms
24 = 8 * area of a trapezoidal base
=> area of a trapezoidal base = 24/8 = 3 square units
*************************************************************************************
Therefore area of a trapezoidal base of each prism with heights 6 and 8 units are 4 square units and 3 square units respectively.

A simple random sample of electronic components wil be selected to test for the mean lifetime in hours. Assume that component lifetimes are normally distributed with population standard deviation of 16 hours. How many components must be sampled so that a 99% confidence interval will have margin of error of 3 hours
Answer:
189 components must be sampled.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
Assume that component lifetimes are normally distributed with population standard deviation of 16 hours.
This means that [tex]\sigma = 16[/tex]
How many components must be sampled so that a 99% confidence interval will have margin of error of 3 hours?
n components must be sampled.
n is found when M = 3. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]3 = 2.575\frac{16}{\sqrt{n}}[/tex]
[tex]3\sqrt{n} = 2.575*16[/tex]
[tex]\sqrt{n} = \frac{2.575*16}{3}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.575*16}{3})^2[/tex]
[tex]n = 188.6[/tex]
Rounding up:
189 components must be sampled.

Step-by-step explanation:
Sam is getting ready for a big date when he realizes that he has no money. his roommate, Bill, also has no money, but he has a credit card. knowing that nobody will let Sam use Bill's credit card, Sam asks Bill to put out a cash advance for $120.00. Bill agrees under the condition that Sam is responsible for all interest that accrues on the cash advance which is 30% interest rate, compounded monthly. The $120 cash advance is repaid in monthly installments over 5 years. How much should Bill ask Sam to pay in interest for the cash advance?
Answer:
b 112.80
Step-by-step explanation:
took test on edge
The interest that accrues on the initial down payment at 30% interest rate is $408 .
What is interest?The term interest refers to money that accrues on a principal sum. It is commonly employed in the parlance of borrowing money.
Since it is a compound interest;
A = P(1 + r/n)^nt
Where;
A = amount
P = principal
r = rate
n = number of times compounded per year
t = total time taken
A = 120(1 + 0.025)^12 × 5
A = $528
A = P + I
I = A - P
I = $528 - $120
I = $408

9x6=54
7.2-1.8=5.4
7.2x5.4=38.88 or 38.9
the figure above, not drawn to scale, consists of a triangle resting on a square of side 5cm. the height of the triangle is 4cm. what is the total area of the figure?
Answer:
5x4x2
Step-by-step explanation:
The total area of the figure id 35 square cm.
What is area?The amount of space taken up by a two dimensional space is called area.
What is the formula for the area of triangle?The formula for the area of a triangle is
[tex]A = \frac{1}{2} (b)(h)[/tex]
Where,
A is the area of triangle.
b is the base of a triangle.
h is the height of the triangle.
What is the formula for the area of square?The formula for the area of square is
[tex]Area = a^{2}[/tex]
Where,
a is the side length of square.
According to the given question.
A triangle is resting on a square.
Side length of square, a = 5cm
So, the area of square = [tex]5^{2} = 25 square cm[/tex]
Also, a triangle with height 4cm.
Since, the triangle is resting on a square.
⇒ Base length of the triangle = 5cm
So, the area of triangle = [tex]\frac{1}{2} (5)(4)= 10 square cm[/tex]
Therefore,
The total area of the given figure = Area of square + Area of triangle
⇒ Total area of figure = (25 + 10) square cm
⇒ Total area of figure = 35 square cm
Hence, the total area of the figure id 35 square cm.

Lalasa and Yasmin are designing a triangular banner to hang in the school gymnasium. They first draw the design on paper. The triangle has a base of 5 inches and a height of 7 inches. If 1 inch on the drawing Is equivalent to 1.5 feet on the actual banner, what will the area of the actual banner be? A 52.5 ft2 B 17.5 ft2 39.375 ft2 D 78.75 ft2
Find the actual Dimensions of the triangle.
Multiply the size of the triangle on paper by 1.5 feet per inch:
Width = 5 x 1.5 = 7.5 feet.
Height= 7 x 1.5 =10.5 feet
Area of a triangle is 1/2 x base x height:
Area = 1/2 x 7.5 x 10.5 = 39.375 square feet.
Answer: 39.375 square feet.
The area of the actual banner is 39.375 feet²
What is scaling?
Scaling is used to increase or decrease the size of a figure so as to create an image.
Given that 1 inch on the drawing Is equivalent to 1.5 feet on the actual banner, hence:
Base = 5 in * 1.5 feet per in = 7.5 feet
Height = 7 in * 1.5 feet per in = 10.5 feet
Area of the actual banner = (1/2) * 7.5 * 10.5 = 39.375 feet²
The area of the actual banner is 39.375 feet²
